STOP MECHANISM FOR TALKING-MACHINES.

Specification of LettersPatent.

Patented Oct. 29, 19075 Application filed April 24. 1907. Serial No. 369.898.

To all whom it may concem:

Be it known that I, JOHN C, STUcKnY, a citizen of the United States, residing at Elizabeth, in the county I of Union and State of New Jersey, have invented certain new and useful ism for 'lalking-liiachinem and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled intheart to which it appertains to make and use the same, reference being had to the accompanying drawings, and to figures of reference marked thereon which form a partthe needle out of engagement with the disk.

r lnother objectof this invention is to provide a deviceof this kind that operates a brake so that when the needle is lifted, the machine is automatically stopped so that if the operator is absent from the machine when it completes its record, the machine will stop and the needle is lifted away from the record and there is no further reproduction of any sounds. This device saves considerable winding, as the record will not rotate any more than is necessary to complete the reproduction.

There is wear and tear saved on the works of the machine, anda better exhibition of the machine can be given with this automatic stoppageof sound on the mechanism. 1

-The invention is illustrated in the accompanying drawings, in which I Figure 1 is a side view of my improveddevice showing its relation to a talking machine, and Fig. 2 is a top view showing a portion of the machine and its relation to the device. Fig. 3 is a face view of the tripping mechanism that releases the machine to stop the rotation .of the disk, and also the means for lifting the sound box and the needle from the record.

I show, in the drawings, any usualform of talking machine 10 employing a rotating plate 11 that carries the record disk 12. In conjunction with this machine is employed a swinging arm 13 pivoted at 14-, as isusual in this class of machines, and the usual sound box 15 is arranged on the end of the swinging arm or tube 13. As is usuallymounted by means of a (I-shaped tube, is arranged a reproducer 16 having a needle -17 project: ing therefrom and adapted to rest on the record disk 12. In machines of this kind the needle is started on the groove of the record, near the periphery of the record disk, and it travels inward following the groove, and when it arrives near the center of the machine the record stops and the needle then runs on, and there is no Improvements in Stop Mechanway of stopping the machine except through a manual manipulation l In my device, however, when ,the sound'box'15 has arrived at a point that brings the needle 17 to the end of the record groove, it is adapted to engage a mechanism to stop it. To support the mechanism for stopping the talking machine, I have deviseda suitable base 18 with the vertical post 19, on which is arranged a block 20 that can be rotatably adjusted or adjusted vertically,

and fastened by means of a set-screw 21. Projecting horizontally from the block 20 is a rod 22 adjustably secured by means of a set-screw 23, and on. the outer edge of the rod 22 is mounted the tripping mechanism 24. This mechanism consists of two circular plates 25 and 26 which has mounted between them on the rod 22, a disk 27. Pivoted at 28, intermediate of its ends, is a lever, one end of which, '29., has a nose 30 that entersa detent 31 in the periphery of the disk, and the other end 32 of the lever projects downward therefrom and'may be provided with a soft covering 33 "which is preferably made of aribbed elastic tubing.

The portion 33 of the lever 32 is the part that is en; gaged by the sound box 15 when it reaches its limit of movement, this being engaged at the proper time because before the record is started, the mechanism is shifted by means of the set-screws 21 and 23, so that by trial it is seen that the needle 17 is exactly at the end of the reproducing groove. Thus when the proper time arrives, and the record is in operation, when the needle arrives at the point where the record stops,

the sound box presses over on the portion 33 of the 10- ver 32, the tooth 30 is drawn out of the detent, and the disk.27 is snapped around by the spring 37 in the direction of the arrows shown on the disk in Fig. 3, and the strip 38, pivoted at 39, is at once drawn upward along with the hooked portion40, which in the meantime has been placed under a strip 41 fastened to the reproducer by reason of the reproducers side movement, and the reproducer is thus in a position to be lifted, and when the above described tripping takes the hook 40, cooperating with the plate 41, lifts .the reproducer so that its needle is clear of the record. A cut-away portion 36 is supplied on the disk so that when the disk is in its operated position, after lifting the reproduc'er, in other words before it is set, it allows "the tooth 30 to occupy the position shown in Fig.3,so

that it-idoes not bear on the outer periphery of the disk 27, and the portion 33 .of' the lever 32 will take place at the proper time. If this cut-away portion were not present, the nose would rest against the outer periphery of the disk 27, and when the apparatus was set'the portion 33 would be enabled to drop, slightly, by reais in the proper position for operation, when the apparatus is adjusted before it is started and the tripping from the disk 27 is a stud 35 carrying a soft covering end of a rod 43, mounted by means of a block 44 on a pivot 4.5. This rod 43 is thus violently thrown in one direction, and the corresponding movement of the rod 46 is caused, and its soft covering or end 47 engages the end 48 of a lever which is pivoted by means of the screw 49 and is normally held in position by a spring 50, which spring, however, is weak and only sufficient to prevent the lever fromhaving an absolutely ,iree movement. The other' end oi'the lever has a nose 51 that is adapted to be thrown into and out of engagement with the bar 52: Thus when the mechanism is tripped, as before described, the end 47 of the rod 46 throws xe lever by engaging its end 48, and the nose 51 is thrown out of engagement with the latch plate 52 which is mounted on a shalt 53, and a spring 55 throws the latch plate 52 over along the shaft 55, which shaft also supports the block 54 for holding the pivotal support 49. Below the shaft 53 and parallelthereto is a rod 56, and a spring 57, on the rod, bears against a slotted collar 58 in which the end 59, which is preferably forked, fits so as to move it in unison therewith, and by means oia coupling 6-1 and a screw 62, the'slraft G3 is thrust forward, and the end 64 hictionally engages the periphery of the rotating plate ll to stop the machine. The rod 63 is arrangodin a bearing 65 that is secured by suitable screws 66 to the box of the machine 10.

This apparatus provides a quick and noiseless stopping of a talking machine, when the reproduction oi a record is complete, and the reproducing needle is removed from the record at the same instant, not damaging the needle and providing for no unnecessary scratching on a record, the'devicebeiug set before the record is started by moving the needle over to the point where the record stops, and adjusting the tripping lever against the sound box, and then when a record is started the above described operation causes a prompt cessation of all sound when the record is through.

Having thus described my invention, what I claim is:-
